Hi Stardust, usually Network will work best to make something resembling a sheet of material which may have curves in it but still has one overall shape to it. Think of something like a sheet of rubber which can be bent or stretched somewhat but not to extremes. It looks like the layout you are trying to use there has so much variation in shape especially with the narrow inward areas with tight bends at their tips, that it's not likely that you'll get a good result from trying to do that in one single go of Network.

Depending on what the final result is supposed to look like, it may be better to build a broader shape initially without any divots between the sections and then cut away the divots later.

Or if the sections don't follow one overall continuous form are a bit disjoint because they are bent at different angles in their winged areas, it would then be better to build each section separately rather than trying to do it all in one go.

If you have any photos of the chair and could post your 3DM model file with your current curves in it, that might help to get some better feedback.
